LOOM.

SPECIFICATION forming part of Letters Patent No. 596,444, dated December 28, 1897. Application filed J'une.21,l897. Serial No. 641,600. (No model.)

To all whom it may concern.-

Be it known that WeflVILLIAM B. FIT'lZ and PETER REILLY, of Oakdale,county of Worcester, State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In many classes of looms for weaving it is necessary that the shuttle be properly positioned in the shuttle-boxthat is, that the shuttle shall occupy a certain definite position in the box-in order that mechanism which depends for its proper operation upon the definite position of the shuttle in the sh uttle-box shall be perfectly free to act whether such mechanism comprises filling-supplying means, some form of filling-feeler or detector, or some other device.

This invention has for its object the prod uction of means for normally acting upon the shuttle to accurately position it in the shuttle-box, said means being arranged and adapted to yield should the location of the shuttle relatively thereto preclude entirely the proper positioning of the shuttle-that is, if the shuttle is so far from its proper position that under such circumstances the filling-supplying mechanism, filling-feeler, or other device would not even tend to operate.

Figure 1,in plan view,shows a sufficient portion of a lay and its shuttle-box to be understood with our invention applied thereto, the shuttle being shown as properly positioned. Fig. 2 is a similar view broken off with the lay back and the shuttle-box empty and ready to receive the shuttle. Fig. 3 is a transverse sectional view on the line 0c 00, Fig. 1,1ooking toward the right. Fig. 4 is a plan View of the parts shown in Fig. 1,the lay coming forward, but the shuttle being so far out of the shuttie-box that the positioning device cannot act to position the shuttle; and Figs. 5 and 6 are details to be referred to.

The lay A is provided with a shuttle-box B of usual or well-known construction, the picker-stick A being shown in Fig. 1. A

bracket a is secured to the lay near the open end or mouth of the shuttle-box, and on said bracket is fulcrumed at a the shuttle-positioning device, shown as an arm Z), bent outwardly at b and carrying on :its extremity a pad b of suitable material having a depression 13 therein (see Fig 5) to receive the metal point S of the shuttle S. The arm has at the other side of the fulcrum a an extension 12 of less width than the arm (see Fig. 3) and bent at U, a spring 5 normally retaining the positioning device in the position shown in Fig. 2 against a stop 3, leaving the mouth of the shuttle-box open.

On the breast-beam A is rigidly secured a guide d, having its rear end extended beyond the breast-beam to form a bunter 61, while a sliding bunter f is mounted in the guide d, said bunter being longitudinally slotted at f to receive the attaching bolts or screws 5 of the guide.

As best shown in Fig. 3, the outer end of the sliding bunter is downturned at f and has secured thereto a rod f extended through an opening in the loom-frame A said rod being shown as surrounded between said part of the frame and its head f with a spiral spring 5', stronger than the spring 3.

The fixed bunter d is in the plane of the extension 19 of the positioning device, while the sliding bunterf is in the plane of the arm Z7 and in the path of the bent or cam portion Z7 thereof, the bunter f normally extending considerably beyond the fixed bunter cl.

Now if the shuttle has entered the shuttlebox and has rebounded slightly or has not been thrown quite fully thereinto as the lay beats up the bunter f will engage the cam 19 and will swing the positioning device on its fulcrum in the direction of the arrow 10, Fig. 2, the continued movement of the lay moving the part b of the extension b into the path of the fixed bunter d. As the lay completes its forward movement the bunter (1 will complete the throw of the positioning device, the pad b acting on the end of the shuttle and definite position, as shown in Fig. 1. The

recess 19 receives the shuttle-point and prevents direct engagement of the pad therewith. So long as the shuttle is so fliciently within the box to permit of the positioning device acting upon itat or near its tip the shuttle will be moved into proper position in the box. It sometimes happens, however, that the shuttle will be so far out of the box, as in Fig. 4, that the positioning device cannot act to push it into position, and in such case the shuttle holds the positioning device from completing its movement. At such time the springs of the sliding bunter f will yield as the lay comes forward and the extension 19 will not be moved far enough to bring it into the path of the fixed bunter 61, thus providing thenecessary yield or give to the parts when the position ing device cannot be operated normally.

Filling-supplying mechanism or a fillingfeeler or detecting device will not be operated unless the shuttle is in proper or nearly proper position in the shuttle-box, a shuttle-feeler and the mechanism cooperating therewith being shown in United States Patent No. 527 ,014, dated October 2, 1894, and when the shuttle is so far out that the positioning device herein described cannot operate normally to properly position the shuttle there will be no tendency of mechanism or devices depending upon the proper position of the shuttle to operate.

Our invention is not restricted to the precise construction and arrangement herein shown, as the same. may be modified or rearranged without departing from the spirit and scope of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a loom, the lay provided with a shuttle-boX, and yielding means to normally act to engage and insure the proper positioning of the shuttle in the shuttle-box, said means yielding when the location of the shuttle precludes positioning thereof, substantially as described. v

' 2. In a loom, the lay provided with a shuttie-box, a positioning device to normally engage and insure the proper position of the shuttle in the shuttle -box, and actuating means therefor, including a yielding member, whereby stoppage of movement of said device by abnormal location of the shuttle may occur without breakage of the parts, substantially as described.

3. In a loom, the lay provided with a shuttle-box, a device to normally engage and insure proper positioning of the shuttle in the shuttle-box, and controlling means for said device, including a yielding bunter, substantially as described.

4:. In a loom, the layprovided with a shuttle-box, a device to normally insure proper positioning of the shuttle in the shuttle-box, and a yielding and a fixed bunter to normally act successively upon and operate said device, the yielding bunter receding when the position of the shuttle prevents the operation of the positioning device, substantially as described.

5. In a loom, the lay provided with a shuttle-boX, a device to normally engage and insure proper positioning of the shuttle in the shuttle-box, a spring to move said device in to inoperative position, and actuating means for the positioning device, comprising a fixed and a yielding bunter, substantially as described.

6. In a loom, the lay provided with a shuttie-box, a device to normally insure proper positioning of the shuttle in the shuttle-box, and controlling means, including a yielding member, to positively move said positioning device under normal conditions, the yielding member acting when the positive movement of the positioning device is prevented,'substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
